The most common reasons for an account to be blocked are:
1 - Spam
2 - Piracy
Blocking on suspicion of piracy occurs when our security system identifies that a user has made several downloads/accesses of the same purchase via different IPs/networks. This blocking is done to guarantee your security, as this type of behavior on your account indicates that it may be being used by someone else.
3 - Mass registration of products
4 - Multiple login attempts
This blocking occurs when there are too many failed login attempts. It is done for security reasons, as this type of behavior may indicate that a third party is trying to access your account.
5 - Underage user as a creator/affiliate/co-creator
